Question

我试图通过Python中的代理服务器访问Web。我正在使用请求库，我在验证我的代理时遇到问题，因为我使用的代理需要密码。

proxyDict = { 
          'http'  : 'username:mypassword@77.75.105.165', 
          'https' : 'username:mypassword@77.75.105.165'
        }
r = requests.get("http://www.google.com", proxies=proxyDict)

我收到以下错误：

Traceback (most recent call last):
File "<pyshell#13>", line 1, in <module>
r = requests.get("http://www.google.com", proxies=proxyDict)
File "C:\Python27\lib\site-packages\requests\api.py", line 78, in get

ValueError: invalid literal for int() with base 10: 'h6f2v6jh5dsxa@77.75.105.165'

我该如何解决这个问题？

提前感谢您的帮助。

Answer 1

您应该从proxyDict中删除嵌入的用户名和密码，然后使用auth参数。

import requests
from requests.auth import HTTPProxyAuth

proxyDict = { 
          'http'  : '77.75.105.165', 
          'https' : '77.75.105.165'
        }
auth = HTTPProxyAuth('username', 'mypassword')

r = requests.get("http://www.google.com", proxies=proxyDict, auth=auth)

Answer 2

我在Windows上遇到过类似的问题，发现让requests工作的唯一方法是在我启动Python之前将代理设置为环境变量。对你来说，这将是这样的：

set HTTP_PROXY=http://77.75.105.165
set HTTPS_PROXY=https://77.75.105.165

您可能还想检查是否需要特定端口，如果是，请在网址后面设置。例如，如果端口是8443，则执行：

set HTTP_PROXY=http://77.75.105.165:8443
set HTTPS_PROXY=https://77.75.105.165:8443

Answer 3

您可以使用urllib库。

from urllib import request
request.urlopen("your URL", proxies=urllib.getproxies())

请求库的Python代理错误
